In the future there’ll be time-traveling pranksters who do stuff like go back in time and change Christopher Columbus’s name to Christopher Indigenous People then watch the alt-universes forking process go crazy. Eventually there’ll be lateral fights between different alt-universes branches. It’ll start out as fun, just a bunch of neighborhood punks screwing with each others’ universal reality — think gaslighting meets neutron star — but then the universal history cops’ll get involved.
